Spacelift Audit Trail Events Collector with AWS

Terraform module setting up a collector that receives Audit Trail events sent by Spacelift and stores them in AWS S3. This is a fork from Spacelift's example module maintained by Masterpoint.

Usage

module "collector" {
  source = "git::https://github.com/masterpointio/terraform-spacelift-events-collector-audit-trail.git?ref=v1.0.0"

	# Add inputs described below as needed
}

Architecture

The main resources for this module are:

• Courier: A Lambda function that exposes a URL (see the courier_url output) and forwards incoming events to a Kinesis Firehose Delivery Stream.
• Stream: A Kinesis Firehose Delivery Stream that buffers events forwarded by the Courier and eventually sends them in batches to the Storage.
• Storage: An S3 bucket that stores the events (see the storage_bucket_name output).

random	~> 3.1

Inputs

Name	Description	Type	Default	Required
additional_tag_map	Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id. This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration.	map(string)	{}	no
attributes	ID element. Additional attributes (e.g. workers or cluster) to add to id, in the order they appear in the list. New attributes are appended to the end of the list. The elements of the list are joined by the delimiter and treated as a single ID element.	list(string)	[]	no
buffer_interval	Buffer incoming data for the specified period of time, in seconds, before delivering it to the destination	number	300	no
buffer_size	Buffer incoming events to the specified size, in MBs, before delivering it to the destination	number	5	no
cloudwatch_logs_retention_days	Keep the Cloudwatch logs of the infrastructure (Lambdas & Kinesis Firehose) for this number of days.	number	14	no
context	Single object for setting entire context at once. See description of individual variables for details. Leave string and numeric variables as null to use default value. Individual variable settings (non-null) override settings in context object, except for attributes, tags, and additional_tag_map, which are merged.	any	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "descriptor_formats": {}, "enabled": true, "environment": null, "id_length_limit": null, "label_key_case": null, "label_order": [], "label_value_case": null, "labels_as_tags": [ "unset" ], "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {}, "tenant": null }	no
delimiter	Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
descriptor_formats	Describe additional descriptors to be output in the descriptors output map. Map of maps. Keys are names of descriptors. Values are maps of the form {<br/> format = string<br/> labels = list(string)<br/>} (Type is any so the map values can later be enhanced to provide additional options.) format is a Terraform format string to be passed to the format() function. labels is a list of labels, in order, to pass to format() function. Label values will be normalized before being passed to format() so they will be identical to how they appear in id. Default is {} (descriptors output will be empty).	any	{}	no
enabled	Set to false to prevent the module from creating any resources	bool	null	no
environment	ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'	string	null	no
id_length_limit	Limit id to this many characters (minimum 6). Set to 0 for unlimited length. Set to null for keep the existing setting, which defaults to 0. Does not affect id_full.	number	null	no
label_key_case	Controls the letter case of the tags keys (label names) for tags generated by this module. Does not affect keys of tags passed in via the tags input. Possible values: lower, title, upper. Default value: title.	string	null	no
label_order	The order in which the labels (ID elements) appear in the id. Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.	list(string)	null	no
label_value_case	Controls the letter case of ID elements (labels) as included in id, set as tag values, and output by this module individually. Does not affect values of tags passed in via the tags input. Possible values: lower, title, upper and none (no transformation). Set this to title and set delimiter to "" to yield Pascal Case IDs. Default value: lower.	string	null	no
labels_as_tags	Set of labels (ID elements) to include as tags in the tags output. Default is to include all labels. Tags with empty values will not be included in the tags output. Set to [] to suppress all generated tags. Notes: The value of the name tag, if included, will be the id, not the name. Unlike other null-label inputs, the initial setting of labels_as_tags cannot be changed in later chained modules. Attempts to change it will be silently ignored.	set(string)	[ "default" ]	no
lambda_logs_verbose	Include debug information in the Lambdas processing logs.	bool	false	no
name	ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'. This is the only ID element not also included as a tag. The "name" tag is set to the full id string. There is no tag with the value of the name input.	string	null	no
namespace	ID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally unique	string	null	no
python_version	AWS Lambda Python runtime version	string	"3.9"	no
regex_replace_chars	Terraform regular expression (regex) string. Characters matching the regex will be removed from the ID elements. If not set, "/[^a-zA-Z0-9-]/" is used to remove all characters other than hyphens, letters and digits.	string	null	no
s3_lifecycle_configuration_rules	A list of lifecycle V2 rules for the S3 bucket where the audit trail events are stored. See example usage https://github.com/cloudposse/terraform-aws-s3-bucket or on AWS docs.	list(object({ enabled = optional(bool, true) id = string abort_incomplete_multipart_upload_days = optional(number) # filter_and is the and configuration block inside the filter configuration. # This is the only place you should specify a prefix. filter_and = optional(object({ object_size_greater_than = optional(number) # integer >= 0 object_size_less_than = optional(number) # integer >= 1 prefix = optional(string) tags = optional(map(string), {}) })) expiration = optional(object({ date = optional(string) # string, RFC3339 time format, GMT days = optional(number) # integer > 0 expired_object_delete_marker = optional(bool) })) noncurrent_version_expiration = optional(object({ newer_noncurrent_versions = optional(number) # integer > 0 noncurrent_days = optional(number) # integer >= 0 })) transition = optional(list(object({ date = optional(string) # string, RFC3339 time format, GMT days = optional(number) # integer > 0 storage_class = optional(string) # string/enum, one of GLACIER, STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING, DEEP_ARCHIVE, GLACIER_IR. })), []) noncurrent_version_transition = optional(list(object({ newer_noncurrent_versions = optional(number) # integer >= 0 noncurrent_days = optional(number) # integer >= 0 storage_class = optional(string) # string/enum, one of GLACIER, STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING, DEEP_ARCHIVE, GLACIER_IR. })), []) }))	[]	no

stage	ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'	string	null	no
tags	Additional tags (e.g. {'BusinessUnit': 'XYZ'}). Neither the tag keys nor the tag values will be modified by this module.	map(string)	{}	no
